}Best text color
Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #1EA76C is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #3adc97 as text on that neutral, and that neutral as text on #3adc97.

Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.
Color scale — 50 to 950
A Tailwind-shaped ramp built around this exact hex. #3adc97 is pinned to step 500; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Not a palette — a role sheet. Each swatch answers one question you will hit while building the component.
Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.
This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.
Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#3adc97, answered
What color is #3adc97?
#3adc97 is a balanced vivid green, closest to Medium Spring Green (ΔE2000 7.3). It sits at 154° on the hue wheel with 70% saturation and 55% lightness, which reads as cool.
What is the RGB value of #3adc97?
rgb(58, 220, 151) — 58 red, 220 green and 151 blue out of 255, or 22.7% / 86.3% / 59.2% by channel.
What is #3adc97 in HSL and HSV?
hsl(154, 70%, 55%) and hsv(154, 74%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #3adc97 a light or a dark color?
It is a light color. Relative luminance is 0.5432 and perceived brightness is 70%, so black text on it reaches 11.86:1.
Should I use black or white text on #3adc97?
Black. It scores 11.86:1 against #3adc97, versus 1.77:1 for white — AAA at any size.
Is #3adc97 accessible on a white background?
#3adc97 on white scores 1.77:1, which fails WCAG AA at every size. Darken it to #178456 to reach 4.5:1, or #11613F for 7:1.
What is the complementary color of #3adc97?
#DC3A7F sits directly opposite on the wheel. Softer options are the split-complements #DC3AD0 and #DC463A, which give the same contrast with far less vibration.
What colors go well with #3adc97?
For interface work: #F4FAF8 as the surface, #C0EDD9 for borders, #4B9B79 for secondary text, #E135A9 as an accent and #136C46 for hover and pressed states. For a palette, the analogous pair #3ADC46 and #3AD0DC stays calm, while #DC3A7F is the loudest partner.
What is #3adc97 in CMYK for printing?
cmyk(74%, 0%, 31%, 14%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #3adc97 warm or cool?
Cool — it scores 77 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #3ADC5B; nudged cooler, #38DED4.
Which Tailwind color is closest to #3adc97?
The green family — its 500 step is #22c55e, ΔE2000 9 away. That is a visible difference, so define #3adc97 as a custom token rather than reaching for the built-in.
How do I use #3adc97 in Tailwind CSS?
Inline it as an arbitrary value with bg-[#3adc97] or text-[#3adc97], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.
What is #3adc97 with 50% opacity?
rgba(58, 220, 151, 0.5), or #3adc9780 in eight-digit hex. Over white that composites to #9DEECB; over black, #1D6E4C.
Is #3adc97 a web-safe color?
No. The nearest web-safe colour is #33CC99, ΔE2000 5.1 away. The palette only matters for legacy displays and some email clients now.
What does the color #3adc97 mean?
As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.
What gradient works with #3adc97?
The safest is same-hue elevation: linear-gradient(135deg, #6EE5B2, #3adc97 45%, #136C46). For more colour, a short hue run to #259AD2 keeps it rich without turning muddy.
